BACKGROUND Technical Field

The present disclosure relates to transmission methods and devices inwireless communication systems, and in particular to a scheme and adevice for measurement in wireless communication.

Related Art

Application scenarios of future wireless communication systems arebecoming increasingly diversified, and different application scenarioshave different performance demands on systems. In order to meetdifferent performance requirements of various application scenarios, the3^(rd) Generation Partner Project (3GPP) Radio Access Network (RAN) #72plenary session decided to conduct the study of New Radio (NR), or whatis called fifth Generation (5G). The work Item (WI) of NR was approvedat the 3GPP RAN #75 plenary session to standardize the NR. Compared withthe existing LTE systems, 5G NR has an outstanding feature of supportingmore flexible Numerologies, which includes Subcarrier Spacing (SCS) andCyclic Prefix (CP), and more flexible frame structures, such as ofmini-slot, sub-slot and slot aggregation. With such flexiblenumerologies and frame structures, various new business requirementswill be better satisfied, especially in highly diversified verticalindustries.

In response to rapidly growing Vehicle-to-Everything (V2X) traffic, 3GPPhas started standards setting and research work under the framework ofNR. Currently, 3GPP has completed planning work targeting 5G V2Xrequirements and has included these requirements into standard TS22.886,where 3GPP identifies and defines 4 major Use Case Groups, coveringcases of Vehicles Platooning, supporting Extended Sensors, AdvancedDriving and Remote Driving. At 3GPP RAN #80 Plenary Session, thetechnical Study Item (SI) of NR V2X was approved.

SUMMARY

A stricter payload balance control is a significant characteristic thatdifferentiates V2X from traditional cellular network, since effectivepayload control can reduce the probability of business conflicts andimprove transmission reliability, which are critical factors forsuccessful V2X. In LTE V2X system, however, a measurement mechanism forpayload control is designed based on a single Numerology, namely, 15 kHzSCS, normal length of CP and 1 ms of subframe length, making itimpossible to meet the requirement of more flexible Numerology of 5G NRV2X.

In FIG. 3 , the radioprotocol architecture between a first-type communication node (UE) and asecond-type communication node (gNB, eNB or RSU in V2X), or between twofirst-type communication nodes (UE) is represented by three layers,which are a layer 1, a layer 2 and a layer 3, respectively. The layer 1(L1) is the lowest layer and performs signal processing functions ofvarious PHY layers. The L1 is called PHY 301 in the present disclosure.The layer 2 (L2) 305 is above the PHY 301, and is in charge of the linkbetween the first-type communication node and the second-typecommunication node, and a link between two first-type communicationnodes (UEs) via the PHY 301. In the user plane, L2 305 comprises aMedium Access Control (MAC) sublayer 302, a Radio Link Control (RLC)sublayer 303 and a Packet Data Convergence Protocol (PDCP) sublayer 304.All the three sublayers terminate at the second-type communication nodeof the network side. Although not described in FIG. 3 , the first-typecommunication node may comprise several higher layers above the L2 305,such as a network layer (e.g., IP layer) terminated at a P-GW of thenetwork side and an application layer terminated at the other side ofthe connection (e.g., a peer UE, a server, etc.).
